(01-13) 12:44 PST VACAVILLE -- A Vacaville pastor and three others have been arrested on suspicion of firebombing the home of his ex-girlfriend, police said Monday.

Mark Lewis, 39, the pastor of Fellowship Baptist Church since 2000, allegedly targeted the home of his former girlfriend on Chateau Circle about 3:30 a.m. Thursday, when someone tried to throw a Molotov cocktail into the residence, police said.

None of the six people who were inside sleeping at the time - including three children - was hurt.

According to officials, police officers responding to the incident saw a rental car not far from the home and stopped it.

Newbolt and Broyles told police that they had been staying at the church because they were homeless, authorities said.

The investigation turned to Lewis when police determined that a woman who lives at the home had an active restraining order against the pastor, police said.

Investigators believe Lewis is linked to several other incidents targeting the victim since Christmas, including harassing phone calls, the breaking of her car windows and another arson in which the bushes in front of her home were set ablaze.

All four suspects were arrested on suspicion of arson of an inhabited dwelling. Lewis was also booked on suspicion of stalking and conspiracy.
